Hi RB -
I started school at 8 months sober. I felt ready for it.
Making the change actually helped solidify my sobriety with a fresh start. I met a bunch of folks with similar interests who ONLY know me as a non-drinker. It put that much more distance between myself and alcohol.
I chose to live by myself (rather than live in the dorms or with roommates) so that I could have an alcohol free home.
Let us know what you decide to do.
